Taco adds a Multi-Volt Zone Sentry zone valve for use in hydronic heating and other HVAC systems such as those with fan coils and air handlers. The new mechanical valve allows one actuator to accept input voltages between 120 and 277VAC 50/60HZ. This means one valve effectively replaces about seven standard zone valves. Like the 24VAC version of the Zone Sentry, the Multi-Volt provides similar energy-efficient characteristics for both heating and cooling applications. The valves are available in a normally closed or normally open configuration.
